Final score = Total QSO points $\times$ (Sum of Zone + Country multipliers). Example: $1000~QSO~points\times(30~Zones+70~Countries)=100,000$ (final score).

B. QSO Points

  • The same station may be worked once per band.
  • Points are calculated based on the location of the station worked:
  • Stations on different continents: 3 points
  • Stations on the same continent, but different countries: 1 point
  • Stations in different countries within the North American continent: 2 points
  • Stations in the same country: 0 points (only the multiplier counts).

C. Multipliers

  • Zone: 1 multiplier for each different CQ Zone contacted on each band.
